Ruby’s to_i is more forgiving than people expect. It converts leading numeric characters, then stops as soon as the string no longer looks like a number. And if the string does not start with a number at all, you just get 0.

to_h converts an array of key/value pairs into a hash. If the same key shows up more than once, Ruby keeps the last value it sees, so later entries override earlier ones.

Ruby’s then keeps a chain readable. It passes the previous result into the block, and returns whatever the block returns.

Ruby’s values_at is a quick way to grab multiple values from a hash in one go. No extra indexing. Just the keys you want, in order.

Ruby’s partition splits one array into two. The first array gets everything that matches your condition, while the second array gets the rest.

Ruby shortcut: tally. It counts duplicates in an array and returns a hash of totals.
Great for quick “how many of each?” moments.

Ruby ranges: use .. when you want to include the end value, and ... when you want to exclude it. In this snippet, a includes 3, while b does not.

Freezing a nested array in Ruby only locks the outer array. The inner array is still mutable, so you can change its contents even though the parent is frozen.

New to Ruby?
`each` is for side effects (like printing), not transformations.
It always gives you the original array back.
